    It’s certainly good practice to stagger ring gaps when assembling an engine; wherever possible I try to avoid having a gap on the thrust side of the piston. It’s generally accepted that rings rotate during use, known I believe as cyclic rotation, so all the gaps ending up in line is strange indeed.
  2. If, as you say , the points are there and they are in reasonable condition , the condenser should not be a problem as to a great extent most small engines are not too fussy about the exact farad rating. The main issue will be finding one small enough to fit. I recently found two on fleabay that fitted under the flywheels of two Kawasaki engines. They were Denso, in their original packing and advertised as being suitable for a certain model of Datsun (Nissan) car. At the worst, the condenser can be mounted remotely from the coil and points.
  3. I have just found an Atom application list and interestingly it does not mention Yellow at all , so the module on your danarm may not be an Atom. . It shows Brown as being specifically made for Chainsaws, brushcutters and nylon line trimmers.
  4. The yellow module looks like the Atom that was sold in the UK in the 1980s and, I believe came from Australia. Unlike the “ one size fits all” Nova and Meco modules the Atoms came in colour coded specific applications. We used to fit lots of them and I have no recollection of reliability issues. Somewhere I have a list of all their different colour applications . I still fit Meco modules when rebuilding Villiers F12 and F15 engine’s on vintage Ransomes cylinder ( reel) mowers etc.
  5. What you describe is typical of a safety circuit / switch issue. The machine is saying that it’s not safe to engage the blades - typically the grass bag or deflector not correctly fitted and not pressing in a safety switch; or even the operator not correctly seated.

    Motorcycle repair shops, particularly those dealing with vintage bikes are worth a try. Also look for engine reconditioners.

    Eye! Eye!

    Enter Dynamo bolts on flea bay . £3.00 a time delivered.
  8. Usually, Nylon Line Trimmer. If fitted with a steel blade - Brush-cutter.
  9. Actually a lot of companies do get upset and spend a lot of money protecting their trademarks. In the early 1960s my first job on leaving college was with the Caterpillar Tractor Company and part of my product familiarisation was reading all the trade magazines, noting all the use of the word caterpillar with a small c as a description of a crawler tractor or track . The authors / publishers were then sent a snotty letter pointing out the error of their ways. When I created my former company's web site I used the word Strimmer and even though acknowledging that it was B&D's trade mark I received a three page letter demanding that it was removed immediately - or else!! Now, where's my Biro - sorry, ball point.
  10. Might be worth an enquiry re Digmower to the Museum of Rural Life at Reading. On a point of order, you have a rotary Cultivator and not a Rotavator which was the registered trade mark of the Howard Rotavator Company and should not be used on any machine not manufactured by them.
  11. Yes, found the original reference to the condenser. Certainly an interesting form of construction that would seem to have stood the test of time.
  12. A great thread and wonderful workmanship . Ignition - unless I’ve missed it, there’s no mention of the condenser, has it been changed? Judging from the number of faulty / weak condensers that I change on not quite so old engines, it may be worth a punt.
  13. Presumably from the same company that made the Mole Grips?

    Just need a selection of bits of tube etc to support the new bearings on the appropriate inner or outer race so avoid "brinelling" the tracks before they've done anything!.

    Pressure wash now, fit new bearings later!! Seriously though, three inverted food tins over the spindle housings may save a bit of grief down the line.
